32.3 Deferred Tax Assets, Liabilities, and Valuation Allowances
Key Takeaways
- ASC 740 income tax tasks in the 2026 FAR Blueprint include current tax payable/receivable, deferred tax assets and liabilities, the provision entry, valuation allowances, and uncertain tax positions.
- Deferred tax liabilities (DTL) arise from taxable temporary differences; deferred tax assets (DTA) arise from deductible temporary differences, operating loss carryforwards, and tax credit carryforwards.
- Deferred taxes are measured using ENACTED tax rates expected to apply when the temporary difference reverses - never proposed rates.
- Record a valuation allowance when it is more likely than not (>50%) that some portion of a DTA will not be realized; on a classified balance sheet ALL deferred taxes are noncurrent.
- Permanent differences (municipal interest, fines, certain meals) affect the effective tax rate but create no deferred taxes.
The Tax Provision Is A Bridge
Accounting for income taxes under ASC 740 starts with one idea: financial reporting and tax law often recognize the same item in different periods. FAR tests whether you can bridge pretax financial income to taxable income, compute current tax payable or receivable, recognize deferred tax assets and liabilities, evaluate valuation allowances, and record the provision entry. The 2026 Blueprint lists all of these in Area III.
Current Versus Deferred Tax
Current tax is based on taxable income under enacted law for the current year. Deferred tax is based on temporary differences that will affect taxable income in future years as related assets are recovered or liabilities settled. Total income tax expense on the income statement equals current tax expense/benefit plus deferred tax expense/benefit, adjusted for valuation allowance changes.
| Difference Type | Example | Deferred Tax Effect |
|---|---|---|
| Taxable temporary difference | Tax depreciation exceeds book depreciation early in life | Deferred tax LIABILITY |
| Deductible temporary difference | Book warranty/bad-debt accrued before tax deduction | Deferred tax ASSET |
| Operating loss carryforward | Current NOL reduces future taxable income | Deferred tax ASSET |
| Tax credit carryforward | Unused credit reduces future tax | Deferred tax ASSET |
| Permanent difference | Municipal bond interest; nondeductible fines | NO deferred tax |
A DTL means future taxable income will be higher because of past events. A DTA means future taxable income or tax payable will be lower if the benefit is realized.
Measurement Rules
Measure deferred taxes using enacted tax rates expected to apply in the years the temporary differences reverse. Do not use proposed rates. If a new rate is enacted before the financial statements are issued, remeasure the DTAs and DTLs in the period of enactment and record the effect in income from continuing operations unless a specific exception applies.
Under U.S. GAAP, current/noncurrent split is no longer a challenge: on a classified balance sheet all DTAs and DTLs are presented as noncurrent, netted by tax jurisdiction. The exam is more likely to ask whether a difference is temporary or permanent, whether it creates a DTA or DTL, and how the change affects the entry.
Worked Example
Pretax book income is $600,000. Tax depreciation exceeds book by $100,000 (taxable temporary difference -> DTL) and book accrues $40,000 of warranty not yet deductible (deductible difference -> DTA). Enacted rate 21%. Taxable income = $600,000 - $100,000 + $40,000 = $540,000; current tax = $113,400. DTL increases by $100,000 x 21% = $21,000; DTA increases by $40,000 x 21% = $8,400. Net deferred tax expense = $21,000 - $8,400 = $12,600. Total tax expense = $113,400 + $12,600 = $126,000 (equal to $600,000 x 21%, ignoring permanent items).
Valuation Allowance Logic
A DTA is recognized in full, then reduced by a valuation allowance if it is more likely than not (>50% likelihood) that some or all will not be realized. The allowance is a contra-asset that increases income tax expense when established/increased and decreases expense when released.
- Negative evidence: cumulative recent losses, expiring carryforwards, history of unused benefits, unsettled circumstances threatening profitability.
- Positive evidence: existing taxable temporary differences that will reverse, strong future taxable income projections, prudent tax-planning strategies, firm sales backlog.
Objective negative evidence such as a three-year cumulative loss is hard to overcome with optimistic forecasts alone.
Uncertain Tax Positions (Two Steps)
First, recognition: is the position more likely than not to be sustained on its technical merits (assuming examination)? If not, recognize no benefit. Second, measurement: recognize the largest amount of benefit with a greater-than-50% cumulative probability of being realized on settlement.
Provision Entry Pattern
| Account | Debit Or Credit |
|---|---|
| Income tax expense | Debit for total provision |
| Deferred tax asset | Debit increases, credit decreases |
| Deferred tax liability | Credit increases, debit decreases |
| Income taxes payable | Credit for current taxes owed |
| Valuation allowance | Credit increases, debit releases |
Effective Rate Reconciliation
FAR often asks you to reconcile the statutory rate to the effective tax rate. Temporary differences do not change the effective rate over time because they reverse; only permanent differences and items like valuation allowance changes, tax credits, and foreign rate differentials move it. For instance, tax-exempt municipal interest lowers the effective rate because it is income for books but never taxable, while nondeductible fines raise it. A frequent simulation deliverable is a schedule starting at "tax at statutory rate" and adding or subtracting each permanent item to arrive at total tax expense.
Common Temporary Differences To Memorize
- Future taxable amounts (create DTLs): accelerated tax depreciation, installment sale gains taxed when collected, prepaid expenses deducted for tax when paid, equity-method income recognized before dividends.
- Future deductible amounts (create DTAs): warranty and bad-debt accruals, deferred compensation, accrued liabilities not yet paid, unearned revenue taxed when received but earned later, capitalized costs amortized faster for books.
The direction matters: a future taxable amount means more tax later, so it is a liability; a future deductible amount means less tax later, so it is an asset.
Worked Provision Entry
Using the earlier example (current tax $113,400; DTL increase $21,000; DTA increase $8,400), the entry is: debit income tax expense $126,000; debit deferred tax asset $8,400; credit income taxes payable $113,400; credit deferred tax liability $21,000. If a valuation allowance of, say, $3,000 were needed against the DTA, you would additionally debit income tax expense $3,000 and credit the valuation allowance $3,000, raising total expense to $129,000.
Simulation Workflow
- Start with pretax book income.
- Remove permanent differences to reconcile the effective rate.
- Identify each temporary difference and its future tax effect.
- Compute current tax from taxable income.
- Remeasure DTAs/DTLs at enacted rates.
- Evaluate the valuation allowance using positive and negative evidence.
- Build the entry; verify expense = current + deferred effects.
A company reports pretax book income of $500,000. Tax depreciation exceeds book depreciation by $80,000, and book warranty expense exceeds tax-deductible warranty payments by $30,000. The enacted tax rate is 25%. Ignoring other items, what NET deferred tax amount is created during the year?
A company has a $200,000 deferred tax asset from loss carryforwards. Recent cumulative losses and expiring carryforward periods make it more likely than not that only $70,000 of the benefit will be realized. What valuation allowance should be reported?
